Help with Sound Setting

[acf6401]

ok i have an Alpine CDA-9883, and lost the settings that the install guy did when I had my amp and sub put in. So i need some help, i have read the manual but dont pretend to understand bass frequency and what not so here are my options if anyone cares to help and/or explain what each does.

Subwoofer: 0~ +15(i remember this being set around 9~10)
Bass Level: -7 ~ +7
Trebel Level: -7 ~ +7
Balance: (i can take care of this one)
Fader: R15 ~ F15 ( i know what this is but i'm sure someone has opinions, i have replaced the door speakers in front and back, no tweeter though)
Defeat: on/off
Bass Center Frequency: 80Hz, 100Hz, 200Hz, 60Hz
Bass Band Width: 1 ~ 4
Bass Level: -7 ~ +7 (this is different from the one above i think, at least they are accessed by pressing 2 different buttons.)
Treble Center Frequency: 10.0kHz, 12.5kHz, 15.0kHz, 17.5kHz
Treble Level: -7 ~ +7 (same note as bass level)
HPF: Off, 80Hz, 120Hz, 160Hz
Loudness: on/off

My music listening ranges from heavy metal, country, rap, and sometimes talk radio.

thanks for all the help!

pretty much everything is set for your preference. the only suggestions I'd make is setting the HPF to off (hoping you have crossovers) and the bass to 60hz if you have a 12" sub or 80hz for 10". If your door speakers sound like mud set the HPF to 80hz or higher to block out the bass to those speakers.

Loudness is generally left on too. but yea far as the rest, it's like an equalizer, everyone sets theirs up different to their ears.

thanks for the input Impact, I have played with the settings a bit and i guess just curious how each one affects the other....if it even does.
